Figure 1. Proportions of ‘facing the viewer’ (FTV) responses as a function of field of view angle.

Data of 11 females and 11 males. The more negative the field of view angle (perspective level) is, the stronger is the perspective cue that the point-light figure is facing away from the viewer. The higher the field of view angle is, the stronger the perspective cue is that the point-light figure is facing towards the viewers. Local shape and size of the dots of the point-light figures were kept constant across perspective levels. Even without local shape and size cues observers seem to easily pick up on the remaining position and motion cues: Mean proportions of FTV responses gradually drop as a function of field of view angle. The effect is stronger for male (blue triangles pointing downwards) than for female observers (red triangles pointing upwards). Female observers respond differently to the same stimuli than male observers. This pattern of results is consistent with the earlier observed ‘observer sex effect’ [22].
